Abstract:
The invention relates to a device (10) for the controlling the temperature of objects, in particular work pieces (16), after a cleaning process, which comprises a controlled temperature zone (14) embodied as a cooling and/or heating area in which a gaseous fluid can circulate around the objects. According to the invention, the controlled temperature zone (14) is formed in a chamber (12) which can be subjected to a fluid flow (58) introduced into said chamber (12).
Abstract:
Die Erfindung betrifft ein Verfahren zum Erzeugen von Prozessdampf durch Verbrennung von getrockneter Braunkohle in einem Dampferzeuger, umfassend die Trocknung von feuchter Braunkohle in einem Wirbelbetttrockner (1) mit von einem Heizmedium durchströmten Wärmetauschereinbauten (2), wobei wenigstens ein Teil des Wassers aus der Braunkohle ausgetrieben und als Brüden aus dem Trockner herausgeführt wird, die Brüden in einer Entstaubungseinrichtung (3) entstaubt werden und die getrocknete Braunkohle in wenigstens einem dem Wirbelbetttrockner (1) nachgestalteten Kühler (6) gekühlt wird. Das Verfahren gemäß der Erfindung zeichnet sich dadurch aus, dass der in der Entstaubungseinrichtung (3) anfallende Braunkohlestaub in direkten Kontakt mit der getrockneten und abgekühlten Braunkohle gebracht wird.
Abstract:
Provided are a continuous drying apparatus and method. The apparatus includes a combustion chamber, a heat exchange chamber, a filter, a mixing chamber, and a drying chamber. Biomass to be dried is loaded into an upper end of the drying chamber and falls on a rotating plate at a bottom of the drying chamber. Heated gas from the combustion chamber is mixed with recycled gas output from the drying chamber, and with recycled gas output from the heat exchange chamber, is filtered and is directed to the mixing chamber. Gas circulates within the mixing chamber and is directed into a lower end of the drying chamber at a drying temperature. The biomass loaded into the drying chamber is dried by the gas, and is extracted off the rotating plate.
Abstract:
The invention provides methods to efficiently reduce the water concentration of raw solid fuels, including low rank coals such as brown coal, lignite, subbituminous coal, and other carbonaceous solids. Efficiently drying these materials at low temperatures significantly reduces greenhouse gas emissions and allows the production of low-rank coals for gasification and liquifaction.
Abstract:
A novel filter assembly (8) for fluid bed granulator, dryer or coater machines (1) which utilize a rigid filter frame (10) consisting of a solid bottom plate (4), a donut-shaped top plate (3) with said top and bottom plates being connected by side rods (5) to form a cage-like frame work. Said rigid filter frame (10) is reusable, around which a pleated (13) reusable flexible filter bag (9) is fitted and clamped (7); top support plate (2) and mounting plate (12) are connected by a threaded rod (6) with a sealing gasket (11) between them. Said filter assembly (8) is located inside said fluid bed machine's exhaust path so that when the process air is drawn through the filter bag (9) it forms around and through the filter frame (10) to cause a pleated (13) accordion effect in such a way that it allows the use of flexible filter media in a configuration that takes less space, gives better support to prevent tearing, is much easier to change and clean between product production run and can be continuously cleaned during operation by alternately providing reverse air flow through it.
Abstract:
A baghouse apparatus for removing particulates from a 100% recycled asphalt pavement dryer exhaust air stream includes a drop out zone section having a water spray operable to initially drench an incoming air exhaust stream with water droplets while increasing air stream velocity, then slow the air stream velocity to cause drop out of particulates >1000pm from the slowed waste air stream, and collect the particulates dropped out of the waste air exhaust stream. The apparatus also includes a cyclonic scrubber section for further cooling the waste air exhaust stream while subjected the stream to a further water spray to condense aerosol vapor into droplets, a prefilter filtration section operable to collect and remove condensed aerosol droplets from the waste air stream; and a coalescing filtration section operable to remove 99% of remaining particulates from the waste air stream before discharge of the air stream to atmosphere.
Abstract:
A dryer (1) is provided. The dryer (1) may include a main body (10) having an inner space formed therein, a fixed drum (200) provided in the inner space of the main body (10), and a tumbling device (51, 52, 53) coupled to the drum (200). The fixed drum (200) may have a non-circular cross-section as it is rotated. The tumbling device (51, 52, 53) may tumble laundry items received in the fixed drum (200) as it slides along an inner circumferential surface of the fixed drum (200).
